Ini thflcon'structibnal =f' 13f ings of the counting drums, are viewed the example shown one 'contact -ring' b and three segmental contact-strips bra The contactrings and strips work in conjunction with "contacts, those appertainingto the :rings bxbeing connected to the source of supplyiand' t-he othersbeing connected to the itensli s tumsis, p eferablyegmdueted in inf l .switches requires to be in the ratio of forty to one. This gearing comprises a-' bevel wheel 6 mounted on the spindle b of the tens and hundreds switch .B which bevel wheel gears with a similar wheel b'* on a spindle B carrying a worm b that gears "with a worm wheel b connected to the thousands and tens "of thousands switchB through the intervention of a clutch device. This clutch device comprises in the example shown a disk B having a sleeve 6 which is rotatably mounted on the spindle b of the switch B and on the inner end of which the aforesaid worm wheel I) is rigidly mounted. The said spindle b is provided at its outer end with a disk B which bears against the outer surface of the disk B connected'to theworm wheel. The disk B is furnished'with a handle a 6? and with a spring plunger B which normally engages as shown with a hole 7) in the disk ,B". The

said plunger, which is arranged in the handle b serveswhen in its engaging position with the hole 6 to transmit the movement of the disk 21?, connected to the worm wheel 6 to the switch B (this worm wheel being driven through theaforesaid gearing,

from a'handle Zr" with which the tens and hundreds switch B is provided). When however the spring plungerB is moved out of operative engagement between the two "disks by moving the handle I) away from its disks Bi, the latter can be actuated by its handle to angularly displace the switch B independently of thetens and hundreds switch B" and without necessitating'the disconnection of the aforesaid bevel and worm. gearing. In this manner the motor A can be causedto actuate the thousands drum a 'in accordance with the amount of displace- -ment given to the switch so that increments of thousands of yards range can be quickly transmitted independently of the range that is transmitted by the switch B. The hole 6 in the disk B insures that the reengagement of the spring plunger B therewith shall take place only after the handle 79 of the tens and hundreds switch B has been actuated to cause the disk B to be angularly displaced to an extent corresponding to the "'displacenient'of the handle I) of the thous: ands and tens of thousands switch B in transmitting the ,large increment of ,range. a

We wish it to be understood that we do not desire to limit the invention to the herein described arrangement of counting drums, nor to the number of motors employed and the number of drums that each motor drives. For example instead of the drum of lowest value constituting the tens drum and being graduated in steps of twenty-five as in the example herein described, it may be graduated in units, and the'drum of highest value in thousands or in tens of'thousands. Inthe former case (i. e. where the drum. of highest value is graduated in thousands) there would be four drums, and when two motors are employed, each would drive twodrums; in the latter case (2'. e. where the drum of highest value is graduated in tens of thousands) there would be five drums, and one motor would drive the units, tens and hundreds and the other would drive the thou-. f sands and tens of thousands drums. 15.1 r c.
